H. pylori strain G27's purine salvage pathway. OD₆₀₀ values for 24-hour growth assays of H. pylori strain G27 ΔsurE (A) and ΔdeoD (B) mutants. (C) The putative purine salvage pathway of H. pylori, with nonannotated enzymes adenosine deaminase (Add) and adenine deaminase (Ade) shown by gray lines. An alternate dGMP production pathway utilizing guanine and dependent on SurE is shown in the box. Starting OD₆₀₀ values were between 0.03 and 0.04. Error bars represent the standard errors of the means. N/A, no additive.
